Problems solved by technology

However, after welding the electrode manufactured by using the existing coating formula, there are problems such as poor weld process performance, high brittleness, and damage to the anti-corrosion ability of the metal surface. In order to prevent the weld from being corroded, it is necessary to coat a layer of anti-corrosion Materials, in order to solve the above-mentioned problems of the welding seam, existing inventions add alumina to the welding core or use pure aluminum welding wire, but the effect is not obvious, there are relatively large limitations, and the manufacturing cost is high, the process is complicated, and it is difficult to popularize

Abstract

The invention provides a formula of a welding rod coating. The formula consists of marbles, quartz, ferrosilicon, ferromanganese iron, calcium carbonate, potassium carbonate, sodium silicate, starch, aluminum oxide, cryolite and sodium silicate. The formula has the beneficial effects that: the problem that a welding seam is liable to corrode after a welding rod is used for welding is solved, tensile strength and impact toughness of a welding seam are strengthened, a brittle transition temperature of the welding seam is reduced, thermal hardness of the welding seam is improved, and surface hardness of the welding seam is strengthened. Moreover, the formula is low in production cost, simple in manufacturing process, wide in scope of application and easy to popularize.

Description

【Technical Field】 [0001] The invention relates to the field of welding materials, in particular to a formula of electrode coating. 【technical background】 [0002] Electrode welding is a welding method in which the base material and the electrode are melted by heating and high temperature. This welding method is widely used and has great flexibility. It can weld a variety of metals and is suitable for various welding positions. It can be used for welding thin plates and For welding thick plates, the equipment is simple, cheap, and easy to maintain. The welding operation does not require complicated auxiliary equipment. However, after welding electrodes manufactured with the existing coating formula, there are problems of poor welding process performance, greater brittleness, and damage to the corrosion resistance of the metal surface. In order to prevent corrosion of the weld, a layer of corrosion protection is required. Materials, in order to solve the above-mentioned problems o...
